Application filed July 18, 1923, Serial No. 652,479. Renewed December 17, 1925.

This invention relates to winding machines,

- and has for its main object-and feature a simple and reliable construction for controlling the top fpressure roll that acts on the top surface 0 the wound material in winding machines.

In the accompanying drawings is shown a concrete and preferred form of the invention in which Fig. 1 is a side elevation of a winding machine, looking in the direction of arrow 1 of Fig, 2.

Fig. 2 is a. vertical sectional view (in the plane of line 2-2 of Fig. 1.

Fig. 3-is a vertical sectional detail view on an enlarged scale on the plane of line 33 of Fig. 2.

Fig. 4 is a sectional view on the plane of line 4--4 of Fig. 3.

The surface winding drums are indicated at 32 and 33. 34 is the winding shaft, 35 the rewound material and 36 is the top pres sure roll. Suitable slitting means may be employed if desired. The top pressure roll is vertically displaceable as the diameter of the rewound material increases and provision mustalso be made whereby the top pressure roll can be lifted at will to remove the wound material. It is important, however, to keep the two ends of the top pressure roll in parallelism as far as possible so as to maintain, as nearly as possible, a uniform diameter of the wound material at both ends.

them across the face of the racks either by displacement of the carriage or' b other means presently to be described. arriage 37 is suspended on flexible connections 42 passing over rotatable members or sprockets 43 and is counterbalanced by weights 44 sliding on ways 45. It will be seen that the center of pinion shaft 40 is, preferably, al-

- most in vertical alinement wlth the center of the top pressure ro-ll so that possible bind,-

ing effect of the parts is obviated. Each sprocket is, preferably, mounted on an indeendent or individual stud shaft 46, this bemg advantageous because if chains 42, or

parts thereof, should stretch unevenly they would exert unequal pull at'opposite sides of the machine and thus tend to interfere with the equalizing action of pinion shaft 40 and pinions 41 engaging racks 39.

The [transmission means for raising or lowering the top pressure roll at will is preferably constructed as follows: Carried by one of the sprockets 43 is a ratchet 47 and engaging with this ratchet'is a pawl 48, said pawl being mounted on gear 49. Both sprockets 43 have roller bearings 50 so as to rotate easily on the stud shafts. Gear 49 is mounted loosely on one of said stud shafts and meshes with another gear 51 carrying sprocket 52. Passing over this sprocket 52 is a flexible connection 53 also engaging a sprocket 54 in the lower part of the machine. 55 is an idler interposed in the path of connection 53. Mounted to move with sprocket 54 is a ratchet 56 and a handwheel 57. 58

indicates a stop pawl engaging ratchet 56.

As the top pressure roll rises in response to the increase in diameter of the wound material sprockets 43 will rotate independently of the back gearing or transmission means controlled by handwheel 57. In other words: Said transmission means. are unresponsive to the turning movements of rotatable members 43. On the other hand by manipulating the transmission means mem-' bers 43 will be actuated, that is: one of said.

members will be actuated thereby lifting the pressure roll. and pinion shaft, and this, in turn, will rotate the other member 43. When lowering carriage 37 pawl 43 must be disengaged from ratchet 47.

We claim: a
